The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0032] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] This utility model embodiment provides an experimental device for analyzing the centripetal force of a circular track, such as... Figures 1-7 As shown, the experimental apparatus for analyzing the centripetal force of a circular track includes:

[0034] A track assembly 100 is arranged on a base plate 320. The track assembly 100 includes a release track 110, a circular track 120, and a retrieval track 130. The release track 110 and the retrieval track 130 are arranged at an angle and staggered. The two ends of the circular track 120 are twisted and connected to the release track 110 and the retrieval track 130, respectively. The retrieval track 130 is set parallel to the ground and is connected to the circular track 120 along the tangent direction of the lowest point of the circular track 120. The tilt angle of the release track 110 is not limited, but the tilted release track 110 is tangent to the circular track 120.

[0035] The track assembly 100 runs on a ball 400. The ball 400 is released on the release track 110 and accumulates kinetic energy through tilting motion to complete circular motion. A pressure sensor is provided at the highest point of the circular track 120 and at the connection between the circular track 120 and the recovery track 130. The pressure sensor is used to analyze the centripetal force at the highest and lowest points of the circular motion and the overweight and weightless state of the ball 400.

[0036] The release mechanism 200 includes a sliding base 220 that slides on the release track 110, an electromagnetic component 210, and a guide rod unit 230 disposed on the release track 110. A support rod 310 providing support is provided below the release track 110, and the support rod 310 is connected to the base plate 320. During movement, the entire base plate 320 is directly transferred. One end of the guide rod unit 230 is connected to the support rod 310. The electromagnetic component 210 is disposed on the sliding base 220. In the initial state, the electromagnetic component 210 generates magnetic force to attract and fix the small ball 400. The height of the release mechanism 200 is greater than the highest point of the annular track 120 to ensure that the small ball 400 can obtain sufficient kinetic energy to run between the annular tracks 120.

[0037] The sliding base 220 includes a sliding block 221 for mounting the electromagnetic component 210 and a drive plate 222. The guide rod unit 230 includes a fixed plate 231, an adapter connecting block 232, and a drive screw 233 and a guide rod 234 connected between the fixed plate 231 and the adapter connecting block 232. The fixed plate 231 is connected to the release rail 110, and the adapter connecting block 232 is connected to the support rod 310. The drive plate 222 is provided with a sliding hole and a guide hole for accommodating the drive screw 233 and the guide rod 234. The number of guide holes is two sets distributed on both sides of the sliding hole.

[0038] The drive screw 233 and guide rod 234 are both arranged parallel to the release track 110. The support bolt 235 provided on the drive screw 233 adjusts the relative height of the sliding base 220 by screwing it in on the drive screw 233, which helps to magnetically attract the kinetic energy of the ball 400 connected to the electromagnetic component 210.

[0039] In this application, the guide rod unit in the release mechanism 200 controls the sliding base 220, which meets the speed control and adjustment needs of the ball 400 during the centripetal force analysis. The support bolt 235 is used to screw into the drive screw 233, which reduces the tedious disassembly and assembly process during height adjustment, simplifies the preparation and disassembly work before and after the experiment, and improves the efficiency of experimental data acquisition.

[0040] As a preferred embodiment of this embodiment, the sliding block 221 is provided with a device cavity 2201 for assembling the electromagnetic component 210. The top surface of the device cavity 2201 and a set of adjacent side surfaces are open structures and communicate with the outside. The side surface is close to the side of the annular track 120.

[0041] The device cavity 2201 is provided with a sliding hole 2202 communicating with the outside on the opposite surface of the open side. The size of the sliding hole 2202 is adapted to the release track 110. The release track 110 can be inserted into the device cavity 2201 from the sliding hole 2202, and the release track 110 extends out of the device cavity 2201 from the side of the device cavity 2201 away from the sliding hole 2202.

[0042] In this embodiment, the electromagnetic component 210 is a prior art electromagnet device, which mainly uses the magnetic force obtained by energizing to magnetically attract the ball 400. Here, the ball is made of a material that can be magnetically attracted. When the magnetic force disappears, the ball 400 will move forward along the track component 100 to complete the circular motion.

[0043] In a preferred embodiment of this invention, the diameter of the sliding hole is larger than the diameter of the driving screw 233, and the diameter of the sliding hole is smaller than the outer diameter of the support bolt 235.

[0044] In this embodiment, the support bolt 235 provides support force to the drive plate 222. To reduce friction, the diameter of the sliding hole is larger than the diameter of the drive screw 233. The guide rod 234 is matched with the diameter of the guide hole to ensure the stability of the experimental device. The purpose of using a double track here is to avoid shaking or rotation.

[0045] In a further preferred embodiment of this utility model, a first pressure sensor is provided at the highest point of the annular track 120, and a second pressure sensor is provided at the connection between the annular track 120 and the recovery track 130; the annular track 120 and the recovery track 130 are tangent and the recovery track 130 is arranged horizontally, and the connection between the annular track 120 and the recovery track 130 is the lowest point of the annular track 120.

[0046] In this embodiment, both the first and second pressure sensors are existing mature pressure sensor devices. They mainly use the pressure on the track. The centripetal force is composed of the support force provided by the track and the weight of the ball 400 itself. By measuring the support force provided by the track, the weightlessness and overweight of the ball 400 can be analyzed. Here, data acquisition and analysis belong to the realm of physics. The device provided in this application mainly helps to simplify the structure for adjusting the corresponding variables during the experiment. The detailed principle will not be elaborated.
